Microalgal lipid is a major
natural feedstock for biodiesel production. However, microalgae-based biofuel
technology comes with obstacles to production, such as high investment and
operating costs. To overcome these problems, nowadays some strategies have been
used during cultivation stage of the microalgae for enhancing biomass and
accumulate lipids and carbohydrates which could be used for biofuel production.
The most common methods applied to microalgae are classified as nutrient stress
and changes in growth conditions that lead to increase the lipid content in the
species without decreasing the growth rate of their potential strains or by
simultaneously increasing both of these. Scenedesmus
sp. are considered to be the most appropriate microalgae to culture commercially
due to their high biomass, lipid and carbohydrate yield. The purpose of this
review was to describe nutrient stress strategy to develop biofuels as a
sustainable alternative to fossil fuels and, in particular, with respect to
nitrogen nutrient limitations, the lipid yield and biomass development in Scenedesmus sp. microalgae. The nitrogen
starvation/limitation strategy that will increase the general economic
feasibility of microalgal lipid production and affect the fatty acid
composition was presented.
